The PD Trination initiative was established in 2005 with the aims to integrate and focus the activities of academia and industry from Norway, Ireland, Scotland and more recently other salmon farming regions.

This industry led initiative has made major contributions to developing a fuller understanding of PD and related conditions by encouraging new and collaborative research, and sharing of results in a transparent manner. Greater knowledge of the risks associated with the development and spread of the disease as well as an understanding of the viral characteristics have helped shape strategies for disease prevention and mitigation for the benefit of the salmon farming industry.

The commitment of farming companies, scientists and governmental institutions to this initiative is matched by the focus and drive of the Steering Committee (SC), which has played a crucial role in these achievements.
